4. Read what two students say about global warming and climate change. Who is more worried about the situation?
(Đọc xem hai học sinh đang nói về sự nóng lên toàn cầu và biến đổi khí hậu. Ai là người lo lắng về các vấn đề này hơn?)
Emma: We are using up fossil fuels like coal and gas very fast. If we carry on like this for much longer, we will have no fuel left and it will be impossible to stop climate change. We must change the way we live and start looking after the environment. Politicians must wake up and take action! We can't put it off!
Tom: It's impossible to come up with a solution that everyone is happy with. We can't just close down all the coal and gas power stations. We rely on fossil fuels for most of our energy. And it's difficult to persuade people to change the way they live. How many people will give up their cars? Not many! We should just learn to live with climate change, not try to stop it.
Emma is more worried. (Emma lo lắng nhiều hơn.)
